The no-code path: hosted x402 proxy
Your API keeps running exactly where it runs today. You register the upstream URL and per-route prices in the PayGate dashboard, and buyers call paygate.arispay.app/{your-slug}/* instead. The proxy returns the 402 challenge, verifies and settles payment, then forwards the paid request upstream.
How it works
1. Create a merchant account at paygate.arispay.app and register your upstream base URL.
2. Declare routes and integer-cent prices in the dashboard.
3. Publish your proxied URL. Unpaid requests get the x402 challenge; paid requests are settled on Base and forwarded with the response returned to the buyer.
Moving to the in-code SDK later is a config change for buyers pointed at your own domain — the wire contract is identical x402 either way.
When to choose the proxy over the SDK
Choose the proxy when you can't touch the deployment (legacy service, third-party host, compliance-frozen repo) or want to validate demand before an engineering change. Choose the SDK when you want payment enforcement in-process and your own domain on the paid URL.

Pricing guidance
- The proxy makes price experiments free: change a route's price in the dashboard and the next 402 challenge advertises it. Use that to search for the volume-maximizing price before committing to one.
FAQ
- Does the proxy see my API's responses?
- The proxy forwards paid requests upstream and relays responses to the buyer, enforcing payment and trust policy at the boundary. Sensitive workloads that can't transit a proxy should use the in-code SDK instead.
- Can I enforce a minimum buyer trust tier?
- Yes — hosted-proxy merchants can set a trust floor so only verified agents can purchase, enforced before settlement.
